Answer:
D. Argument 1, because the example supports the claim that children who play sports become healthier adults.
Explanation:
The argument that is supported by relevant evidence is the first one. It relies on a survey according to which children who play sports become healthier adults. It includes the correct causal relationship - a type of relationship where one thing causes another thing to happen.
This type of relationship isn't present in the second argument. Children getting exercise while their parents work out isn't really related to them being healthier as adults. Them swimming from time to time or playing in a ball pit can't be considered playing sports and will not contribute to their development.
This is why option D is the correct one.
